To all whom it may concern Be 1t known that l, O'r'ro JOSEPH TnoiusGus'ravn RICHARD MARTIN, a sub ect of the King of Great Britain, and aresident of the for I urnaces; and the object of my inven- 10 tion is toprovide a composition which may be termed up into bricks or slabscapable of -withstanding intense heat without burning out and which maybe employed to great advantage tor the lnnngs of furnaces used tor theelectrical smelting of ore or like purposes. I

a My composition consists of the following ingredients combined in theproportions stated. viz

Brick clay 15 parts Intusorial earth 8 parts Soapstone 4 parts Asbestos,6 parts These ingredients are to be thoroughly mixed 1n powder form,and then thoroughly mixed with cold water, in which has been dissolvedsalt to the extent of one-quarter.

(3:) ounce to the gallon, until the consistency is like that of stiffclay and capable of being easily pressed into molds.

The bricks or slabs formed by inoldingare then dried out in the usualmanner for four or five days in a temperature of sixty (60) degrees.after which they are placed in brick kilns and burned hard.

By lining furnaces with bricks or slabs formed out of the abovecomposition. smelting operations in which a great intensity of heat isrequired may be carried on successfully, aS such lining will not burnout with the most intense heat.

I do not, however, confine myself to t e Specification of LettersPatent.

exact proportions of the various ingredients as stated above, nor do Iconfine myself to the use of all the ingredients when making up thecomposition. For instance, the bricks'or slabs could be made from acom.- position consisting of the brick clay and soapstone alone. or ofthe brick clay and infusorial earth alone. or of the brick clay andasbestos alone each of which combinations would produce bricks whichwould give resistance to heat up to a certain degree. but with all theingredients combined in the proper proportions. asset forth in theforegoing. the bricks resulting therefrom are capable of withstanding afar great-erdm tensity of heat than those resulting from any of thecombinations just mentioned.

. What I claim as my invention is 1. The herein described plasticcomposi tion including brick clay and infusorial e: 'th rendered plastic'by'water having dissdlved therein salt in the proportion of onequarterounce to the gallon.

The herein described plastic composition including brick clay,infusorial earth, and soapstone.

3. The herein described plastic composition including brick clay,intu'sorial earth,

soapstone. and asbestos;

'4. The herein described plastic composition consisting of brick clay,infusorial earth. soapstone, asbestos and salt water.

5. The herein described plastic compositiou consisting of brick clayfifteen parts. intusorial earth eight parts. soapstone four parts, andasbestos six parts. rendered plastic by water having dissolved thereinsalt in the proportion of one-quarter ounce to the gallon.
